French Manicure Made Easy Nail pen Device

ABSTRACT

Provided is a nail pen for nail varnish application along a distal perimeter portion of a nail. The claimed invention obviates certain problems associated with the process of applying nail varnish onto the distal-only perimeter of a nail by presenting an apparatus and/or means for applying nail varnish in a controlled, uniform manner along the distal perimeter of a nail. The claimed invention provides a controlled means of disseminating a uniform strip of nail varnish along the distal perimeter of a nail. This desirable outcome is effectuated even for different varnish residue thicknesses and/or varnish colors. Also provided is a nail varnish applicator with a channel made from an impermeable material.

FIELD OF THE INVENTION

The claimed invention obviates certain problems associated with the process of applying nail varnish onto a distal perimeter region of a nail. By way of a non-limiting example, a beautician-assisted or self-administered French manicure procedure may involve the application of varnish, or similar type of nail polish substance, exclusively along a uniform and dimensionally-consistent distal-most region of a nail. Without the use of the apparatus and/or method of the claimed invention, it is possible for the nail varnish to be spread unevenly onto the distal perimeter of a nail due to the shaking of the hand of the individual applying the nail varnish. Due to the fast-hardening chemical characteristics of nail varnish, any imperfections or inconsistencies with the distribution of nail varnish on the distal perimeter of the nail will become bound to the nail surface. The correction of any minor imperfection or inconsistency with the distribution of nail varnish would not be able to be fixed without the removal of any or all of the nail varnish applied to that distal outer perimeter. The present invention obviates this dilemma by presenting an apparatus and/or means for applying nail varnish in a controlled, uniform manner along the distal perimeter of a nail with significantly fewer imperfections or inconsistencies with the distribution of nail varnish on the distal nail perimeter.

SUMMARY OF THE INVENTION

The claimed invention relates to an apparatus and/or means for nail varnish application along a distal perimeter portion of a nail. The claimed invention provides a controlled means of disseminating a uniform strip of nail varnish along the distal perimeter of a nail. This desirable outcome is produced by limiting the portion of the nail surface that contacts the nail varnish applicator; only a fixed length relative to the distal tip of the nail onto which nail varnish is applied is in contact with the nail varnish applicator. Because of the fixed-length-relationship between the distal tip of a nail and the horizontal thickness of the nail varnish applicator, the resulting strip of nail varnish on the distal portion of the nail is uniform and consistent. A nail guide portion adjoins an edge of a nail, and the nail guide portion limits and directs (based upon the outer contour of the nail) the direction and extent of contact made by the varnish, applicator with the surface layer of the distal-most region of the nail. The nail guide portion allows the varnish applicator to render an aesthetically-smooth-and consistent-seeming layer of varnish residue on the surface layer of the distal portion of the nail.

The claimed invention also provides for alternative nail varnish applicator horizontal thicknesses, varnish colors, and/or material compositions. While different users may utilize the claimed invention to produce different preferred horizontal thicknesses, varnish colors, and/or material compositions, the claimed invention still produce the same level of consistency and control during its respective use.

The detachable guide in FIGS. 5A and 5B can have a hollow ring that slide into the bottom of the nail pen in a complementary region (32 as illustrated in FIG. 5C) in such manner that the guide is positioned next to the applicator. FIG. 5D illustrates the guide of FIG. 5B (a ring with the guide portion attached thereto) in position on the nail pen where the guide is positioned next to the applicator.

FIG. 6 illustrates a nail pen with a button (24). This button (24) can be used to push varnish though the varnish reservoir (34) in the nail pen body (33). FIG. 6 also illustrates a nail pen where a unique applicator (25) is used to apply varnish (29). In this embodiment, varnish (29) is comes out only from the opening (27) of applicator tip (26). The sides of the varnish applicator (25) are not permeable, and contain the varnish inside the applicator (25). The tip (26) of the varnish applicator (25) can be shaped like semi-circles (36), where the diameter of each of the semi-circles form the bottom of the tip (26) defined the length of the tip. A gap between the two semi-circles (36) allows varnish to leave the reservoir through opening (27) and be applied to distal portion of a nail (37). Specifically, the applicator (25) is a hollow cylinder with two openings, and in one of the two openings the end of the applicator tapers towards the center with a semi-circular portion to form a rectangular bottom opening (27).

FIG. 7 illustrates a nail pen that is similar to the nail pen of FIG. 6 except that the applicator tip (26) has two flat portions that define the opening of the tip (26) rather than semi-circular parts (36). The detachable guides (35) can be placed on the nail pen illustrated in FIGS. 6 and 7.

FIG. 8 illustrates the nail pen of FIG. 7 with a guide attached thereto. Varnish (29) is applied through the bottom opening (27) of the nail pen to the distal portion of the nail (37). The bottom opening (27) is rectangular, and is formed by two parallel edges. The guide (10) is pressed, against the edge of the nail of a user, and the bottom opening (27) applies the varnish to the distal portion of the nail (37) at a substantially perpendicular position. FIG. 9 illustrates the nail pen of FIG. 7 with a guide that is bent (10 a) at the bottom. The guide (10) bends toward the applicator (25) (or alternatively applicator 14) in relation to the nail pen top portion (2) having a vertical position. The guide can have a first straight (vertical) portion (12) that is parallel to the central axis of the body, followed by a bent portion (10 a) that bends towards the applicator in an upward direction.

FIGS. 10, 11, and 12 illustrate the various views of the varnish applicator (14) with a first end (38) and a second end (39). The first end (38) has a flat rectangular bottom surface for applying varnish. The second end is attached to the nail pen and is in fluid communication with a reservoir (34) containing varnish (29). The varnish travels to the flat rectangular bottom surface 16′. The width of flat rectangular bottom 16′ can be about 2 mm to about 7 mm, such as about 5 mm. The length of flat rectangular bottom 16′ can be about 1 mm to about 1 cm, such as about 1 mm to about 5 mm, such as about 1.5 mm to about 3.5 mm. Other lengths suitable for application of a French manicure to a natural nail can also be used. The length is typically longer than the width, such as about 2-5 times the width.

FIG. 13 is a perspective view of a nail pen with applicator (14). As shown in this figure, the guide (10), inside surface (12) and the flat end (16′) of the varnish applicator (14) have the same length, and have the same alignment, and have a uniform direction.

FIG. 14 illustrates a nail pen with an applicator (14) and a guide (10). The applicator (14) illustrated in this figure is made from an absorbent material, through which varnish moves through primarily by diffusion. The applicator (14) has a rectangular flat-end bottom (16′) for applying varnish to the distal portion of the nail (37). The rectangular flat-end bottom (16′) of applicator (14) is positioned in the nail pen in a perpendicular fashion to the inside surface of the nail guide (12) that is configured to contact the edge of the nail. The length of the rectangular flat-end bottom (16′) is longer than the width (such as by a factor of more than 2, or more than 3, generally 2-5 times longer), and the direction of the length of the rectangular flat end bottom 16′ is perpendicular to the inside surface (12) of the nail guide (10) in relation to a horizontal line in surface (12) (For example the lower straight boundary line on surface 12 shown in FIG. 15). The rectangular flat-end bottom (16′) has a length that defines the length of the French manicure strip placed on the distal portion of the nail. FIG. 15 illustrates the same nail pen as FIG. 14, except a right perspective view is shown. The perspective vies of FIGS. 14 and 15 illustrate the guide (10) extending on both side of applicator (14) in a horizontal fashion (relative to the nail pen being in a vertical position). The guide (10) also extends below the bottom end (16′) of applicator (14).

FIG. 16 illustrates movement of varnish (29) through the nail pen of FIGS. 14 and 15. Varnish (29) moves from reservoir (34) inside of the nail pen to applicator (14), which is made from an absorbent material that allows for movement of varnish (29) primarily by diffusion. The varnish (29) diffuses from top (shown in broken lines in FIGS. 16 and 17) of applicator (14) to the rectangular flat end bottom 16′ of applicator (14). When the flat end bottom (16′) of applicator (14) is contacted with the distal portion (37) of the nail (20) of a human, varnish (29) is applied to the nail (20).

FIG. 17 illustrates the edge of the tip of the nail (22) contacting nail guide inside surface (12). The nail guide inside surface (12) is substantially at a perpendicular or slightly bent position (less than 30 degrees relative to a vertical axis) relative to the distal portion of the nail (37). The inside surface of the nail guide (12) extends to below the edge of the nail tip (22). The user presses the inside surface of guide (12) against the edge of nail tip (22), and then moves the nail pen across the nail tip (22), resulting in deposit of varnish residue to the distal portion (37) of the nail (22) by the flat end bottom (16′) of applicator (14).

FIG. 18 is a perspective view of a nail pen. A button (24) can push varnish out of the reservoir (34) to the applicator tip (26) which in this embodiment is shown with a channel (28) and an impermeable wall around channel (28). Alternatively, varnish (29) can move from the reservoir (34) to the applicator tip (26) via gravitational force and/or diffusion. Diffusion particularly works when the applicator tip is made from an absorbent material.

FIG. 19 illustrates a first end (38) of the impermeable applicator (25) of FIG. 12. First end (38) is in fluid communication with varnish inside of the nail pen. The opening of the first end (38) contacts the distal portion (37) of a nail to apply a strip of varnish.

FIG. 20 illustrates a second end (39) of the impermeable applicator (25) of FIG. 12. Varnish from the nail pen enters the impermeable applicator (25) from a hollow cavity (34) inside of the nail pen.
